While alert, video will stop in Safari of iOS17.x.

The video will not continue after you close the alert dialog.

The behavior can't be detected without invasive code, so we can't workaround it.

Solution:

Don't use alert in production.

Or offer a button of play which will call scanner.show() or scanner.open(), so end user can manually restart video.
